I checked with my dealer and it was around $17K, but that was with me getting a super deal on new one since I know them. Mine is 05 with 14K on it.
They generally go by the black book values and never used the excellent condition column and dont even add for mileage unless you ask and will quickly deduct for high mileage. I would try CarMax first, although they were not even in the ballpark when my son took his CRV to them recently.
